Gaze -- Psychological aspects. ; Facial expression. ; Body language.
The primary goal of the current research was to examine the effect of perceived gaze direction on the perception and processing of facially communicated emotion. There is good reason to believe that gaze direction and facial displays of emotion...
Functional neuroimaging has confirmed a high degree of localization of function in the cerebral cortex of man. In contrast, microstructural analysis has contributed very little to the topographical characterization of cortical areas. In this work I...
Hematopoietic stem cells (HSCs) balance self-renewal with the continuous production of the suitable numbers of lineage-restricted progenitor cells. In this work we demonstrate that the Mixed lineage leukemia 1 (Mll1) gene is essential for this...
Brain mapping via EEG activation is a useful tool of basic neuroscience, and has wide clinical applications as well. The mapping is achieved by means of Event Related Potentials (ERPs), task-related changes in EEG time series. The methodology of...
Community health services -- United States -- Evaluation. ; Health care reform -- United States. ; Medical care -- United States -- Evaluation. ; Evidence-based medicine.
Genetic and immunological tools have been used to study two protozoan parasites, Plasmodium falciparum and Toxoplasma gondii. Toxoplasma gondii provides an excellent model for the study of protozoan parasite biology. Plasmodium falciparum causes...
In large and complex networks such as the Internet and road networks, traffic routing is typically decentralized. Users in the network choose their routes independently to minimize their own delay, leading to complicated and nonintuitive outcomes...
The image of a child standing at the side of a creek and skipping stones across it exemplifies how we tend to mentally separate aquatic habitats from dry land. But there is a constant exchange of materials from land to streams, and vice-versa....
Cytokinins regulate broad aspects of plant growth and development, such as cell division, root and shoot growth, chloroplast development, and leaf senescence. Cytokinins are perceived by a signal transduction pathway that involves receptors,...
History repeated--- A new Dartmouth College Pine Tree, replacing the legendary Old Pin which was cut down in 1895, was dedicated Tuesday (June 13) on the Dartmouth campus in Hanover N.H. Highlight was the appearance of three members of the Class of...
Despite great progress in object recognition techniques, there is a mismatch between traditional approaches and the characteristics of real world vision tasks. We highlight in particular, three closely related areas of mismatch: i) recognition...
Convocation, 1948; front page of the Dartmouth, Friday, October 1, 1948; headlines: Students throng Webster Hall as Convocation service inaugurates Dartmouth's 180th session; Dickey's address highlight ceremony; Council head's statement new...
Arctic soils in the permafrost region store substantially more carbon than is contained in the atmosphere, and are undergoing rapid change associated with anthropogenic climate change. Soil decomposition is an important component of ecosystem...
Autoimmune hepatitis (AIH) is an autoimmune liver disease characterized by immune-mediated necroinflammatory liver damage associated with CD4 + T cell infiltration in liver parenchyma. Despite advances in the understanding of AIH, its etiology...
Cholesterol is essential for the survival of all mammalian cells. Mammalian cells obtain cholesterol via two pathways: it can be endogenously synthesized in the endoplasmic reticulum, or it can be obtained from exogenous sources, mainly through the...
Cyclic diguanylate (c-di-GMP) is a primarily bacterial and nearly universal second messenger used to stimulate a variety of responses from the cell by binding effector proteins. It is created by enzymes called diguanylate cyclases (DGCs) and broken...
Sensing light from the environment using photoreceptors is of great adaptive significance to eukaryotes. A prominent feature of the photochemistry of these receptors is the photocycle length, the time taken to decay from the initial signaling light...
Hypercapnia -- Regulation. ; Carbon dioxide -- Physiological effect. ; Carbon dioxide in the body. ; Brown garden snail -- Respiration. ; Potassium channels.
After more than 150 years of studying the respiratory effects of hypercapnia, the intrinsic neuronal mechanism by which carbon dioxide (CO²) stimulates electrical excitability of respiratory neurons, and hence respiratory drive, is still...
The advent of hypervisors revolutionized the computing industry in terms of malware prevention and detection, secure virtual machine managers, and cloud resilience. However, this has resulted in a disjointed response to handling known threats...
Genome sequencing technology has enabled the identification of genetic variants that are linked with cancer phenotypes, whether these are somatically acquired mutations or common inherited single nucleotide polymorphisms (SNPs). Whereas coding...
Cholera is a diarrheal disease caused by the Gram-negative bacterium Vibrio cholerae. The disease is acquired by oral ingestion of contaminated water or food. In order for Vibrio cholerae to cause the disease cholera, it must produce two important...
Magnetic resonance imaging. ; Nuclear magnetic resonance.
Diffusion-weighted magnetic resonance imaging (MRI) provides unique contrast reflecting the translational motion of water in its microscopic environment. This imaging modality has been shown to highlight infarcted regions within minutes after an...

Landscapes evolve in response to external forcings such as climate and tectonics that influence the pace and patterns of erosion and weathering processes. Furthermore, internal feedbacks between erosion and weathering regulate the expression of...
Sudden infant death syndrome (SIDS) occurs when a sleeping infant experiences a challenge to cardiorespiratory homeostasis which it fails to overcome. Analyses of brain tissue from SIDS cases from around the world consistently show abnormalities in...
Within a species, the abundance of individuals varies in time and space. This dissertation research examines processes giving rise to patterns of spatial and temporal variation in the abundance of multiple species of forest-breeding migratory...
Morbidity and complexity involved in lymph node staging via surgical resection and biopsy could ideally be overcome using node assay techniques that are non-invasive. Visible blue dyes, fluorophores and radio-tracers are often used to locate the...
Though researchers have advocated a more direct link between individual, population, and community processes, translating the behavior of individuals to the dynamics of natural populations and communities has remained a major challenge in ecology....
Space and time in language. ; Space perception. ; Figure-ground perception. ; Psycholinguistics.
Across languages, there exists a relatively small number of spatial prepositions. These terms are used to express the infinite number of possible spatial locations of an unlimited number of different entities in the environment. Previous research...
